Abstract:
Gamma-ray binaries are binary systems that emit most of their radiative output above 1 MeV. Following the detection of five such systems in the past decade, they have been clearly established as a population of galactic GeV and TeV sources. In this review I discuss their recent gamma-ray observational results from Cherenkov telescopes and the Fermi satellite. A common trend has emerged in the high-energy spectra of several of these sources, with the detection of two separate components at GeV and TeV energies that cannot be explained as being emitted from a single region, and here I discuss a possible scenario giving rise to two separate acceleration locations in gamma-ray binaries.
